This Extreme Extruded propellant has gone through some changes since its inception, all the time maintaining the same important burning speed of the past. The kernels were shortened for improved metering and necessary elements were added to make it extremely insensitive to hot/cold temperatures.

Description 2:

Our exclusive line of extruded rifle powders – Hodgdon Extreme™ – was developed to give shooters consistent performance, load after load, in even the most extreme heat and cold.
